SPECIFICATION formingpart of lLetters Patent No. 740,494, dated October 6, 1903.

Application led July 1, `1901` AV.iitenevrefl Marohf1903. Serial No. 147,150. (No model.)

To all whom it may concern:

Be it known that I, JOHN B. WARING, acitizen of the United States, anda resident of East Orange, Essex county, State of New Jersey,

5 have invented new and useful Improvements in Valves, of which the following is especification, reference being had to the accompanyingrdrawings, forming part thereof.

This invention relates to valves adapted 1o for the .regulation or reduction'of pressuresn and for controlling the flow of a fluid from a high pressure to a low pressure, and so regulating the How of the iiuid as to produce a uniform predetermined low pressure or pressure beyond the valve.

My invention consists in the provision of an axiallypivoted conical ported valve for such purpose controlled by the pressure lproduced by the restrictive and regulating aczo tion of the valve, and, further, in the provision of improved means whereby the high pressure tends to press the valve against its seat and also actuates a compensating device tending to press the valve away from its seat;

bination, with means for opposing or equal. izing the duid-pressures upon the valve, ofv additional pressure means whereby a predetermined pressure is exerted to make the 3o valve tight upon its seat.

My invention further consists in improved means wherebyfa very delicate controlling action is had and in various improvements in connection and combinations of parts.

I will now describe the pressure-reducing valve embodying my invention illustrated in the accompanying drawings and will thereafter point out my invention in claims. V- l Figure 1 is a longitudinal vertical section 4o of a reducing-valve embodying my invention.

Fig. 2 is a transverse vertical section of the' same. Y

The casing in the embodiment of my invention shown is a body part formed of a single casting 1 and provided with a high-pressure chamber 2, a low-pressure lchamber 3, and a compensating chamber 4, wherein the` high pressure against the valve is balanced. The end of each of these chambers is covered the valve-seat 17.

5o by a removable cap-f-the cap 5 of the highf pressure chamber, the cap 6 of the low-pressure chamber, and the cap 7 of the compensating chamber. The low-pressure chamber has lateral branches 8 9,' the pressure-piston 10 being located in the branch. 8, shown as a removable cylinder, for greater convenience in construction, and the compensating spring 1 1 being located in the branch 2 and the ends of these branches being covered by removable caps 12 and 13, respectively. A rod 14 from the piston extends loosely through the cap 12, so that the piston receives freely the pressure of the atmosphere at its outer face, and an adjusting-screwl is provided for the compensating spring 11, this screw 15 having a head seated in the cap 13 againstA a packing-ring and having a nut 16 engaging the outer end of the compensating spring l1.

f The valve-seat 17 is shown asof conical forni and seated in'an opening between the high-pressure chamber 2 and the low-pressure chamber 3 and clamped against a shoulder by the externally threaded annular nut 1S.

The valve-seat also has a bearing therein for the valve-stem 19, and this stem also basa bearing in the ring 20, which is clamped against a shoulder in an opening between the low-pressure chamber 3 and the compensating chamber 4, and has a recess formed thereinwithin which is located a pressure block or piston 21, shown as having a ball-and-socket connection with the rear end of the valve- .stem 19, anda diaphragm 22, the outer periphery of which is clampedV against theface of 4the ring 2O bythe annular externally-threaded nut 23, bears against the face of the pressure.- block/21 andtransmits to the valvestem and valve the pressure in the compensating chamber 4, and as this compensating chamber is connected bya duct 24 with the 9o 'high-pressure chamber 2 this .pressure is that of the high-pressure chamber.

The valve 25 is shown as of conical form and tting against the valve-seat 17 and movable rotatively relatively theretoand having 9C a plurality of ports which when the valve is Wideopeu correspond with similar ports in Theconical form of the rotary or oscillating valve permits a very much larger area of ports for a given diameroo ter of valve than a flat valve, while retaining the important feature that the Valve is selfadjusting to compensate for wear and embodying the many Well-known advantages of a conical valve and seat.

It is designed to balance the valve exactly by the pressure from the compensating chamber transmitted by the diaphragm and pressure-bleek. sures there would be no tendency to move the valve in either direction, and therefore no pressure of the valve against its seat. As some pressure of the valve against its seat will be necessary to insure tightness of the valve, I propose to provide this pressure by a pressure-spring 26 between the valve 25 and cap 5 and to provide for each valve a pressure-spring adapted for the pressures under which the valve is to be worked. This pres-- sure-springprovidesapredetermined pressure altogether independent of the variations of the high pressure and just such a pressure as is required to insure tightness of the valve, while the diaphragm compensating device insures a balancing of the duid-pressures under all variations of the high pressure.

The valve is actuated by a controlling mechanism comprising the pressure piston 10, above described, receiving the low pressure against its inner face and the atmospheric pressure against its outer face and having an inner rod 28 engaged by an operating-arm 27 on the valve-stem 19, and the compensating spring ll, above described, engaging a loop at the inner end of the inner piston-rod 28. The construction permits of the employment of an operating-arm 27 of considerable length, whereby a considerable leverage is gained upon the valve and a delicate controlling action assured.

It will be noted that the construction permits ready access to and the insertion and removal of all parts of the valve.

Itis obvious that various modifications may be made in the construction shown in the drawings and above particularly described within the spirit and scope of my invention.

What I claim, and desire to secure by Letters Patent, is-

1. The combination, with a casing having a high-pressure chamber and a low-pressure chamber and a ported valve-seat between said chambers, of a ported axially-pivoted valve and means for actuating the same rotatively, the valve being arranged so that the high pressure tends to press the valve against its seat, and compensating means engaging the valve-stem but permitting rotation thereof independently of the compensating means, whereby the high pressure is also exerted in opposition to the tendency to press the valve against its seat.
